[ applause ] >> reporter: but gingrich's path to the republican presidential nomination is likely to be difficult. romney has more money and better organization in the upcoming caucus states. and there's another potential hurdle for gingrich. florida exit polls show a widening gender gap. more than half of women voters supported romney, less than a third backed gingrich. rick santorum and ron paul skipped florida to begin campaigning out west. both candidates called romney to congratulate him last night. gingrich did not. randall pinkston, cbs news,
